1 Joule IS 1 newton-meter.
Answer:
At top vertical componant of velocity is zero
Answer: 0.22
Explanation: Subtract 0.01kg from 0.23kg
In a vacuum, all objects fall at the same rate. Meaning that the 100 kg ball will fall at the same speed as the 10 kg ball. Assuming that both objects share the same starting acceleration, they will keep that acceleration until the fall is stopped.
In other words, your answer is the first one, Both objects will accelerate at 9.8 m/s
The scientist who discovered the two elements radium and polonium would be Marie Curie in 1898.
Hope this helps!
